To all 1201mm itmay'concem:

Be it known t at II, Wannmar E. Swan-M, a citizen of the United States, residing at Los Angeles, Los Angeles county, ()ali forni-a, :have invented certain new and use ful Improvements in Adding-Machines, of which the .fellow-ing is a specification.

My invention relates to what are com monly known as adding machines by which individual items are: ri-nted, .listed and added, and the object o 'my invention is to so arrange and adapt a machine of this character that the adding mechanism proper may be thrown out of action at the will of theoperator, withrthe result that such machine is enabled to print and list numbers or figures which are not required to be added or totalized as well as to print and list amounts which are to be totalized in the usual and well :known way.

vention finds useful'application for a variety of diflerent classes of accounting work and, for the purpose of affording a clear and definite understanding of my invention I will describe it as employed in the work of listing cotton .sales, which require to be printed not only the price but also the number of each bale of cotton. The amounts representing the prices are listed and-added by the machine in-the ordinary manner, but, of course, thenumbers of the bales require An adding machine embodying my inlisting and not adding.

provides for the throwing out or elimination of the adding feature of the machine when such numbers, which are not 170.b8 added, arebeing printed by the machine.

My invention; is more particularly designed as an improvement upon what is y invention therefore contemplates and commonly known as the Burroughs adding machine, illustrated and described, for instance, inLetters Patent :of the United States Nos. 504,963 and 505,078,'issued to William S. Burroughs on September 12, 1893, but my invention, considered in its broad aspect, is not to be understood as limited in its application to the Burroughs machine, in-asmuch as the same may he 'embodied and incorporated .in adding ma character and used for.

chines of similar similar purposes.

Inlthe drawings, Figure 1 is a plan view of. a Burroughs adding, machine, with the and are each provided with the rearward 'end theneoi partially broken away to exipose certain of the parts of my attachmerit comprising 'my invention; Fig. '9. a sectionafl (elevation of the 'le'i t side "of the machine; Fig. 2 a d'c'ta i'l o'if a portion-or lever $1411; Fig. 3 an end elevation of machine showing -the principal parts con cerned; Fig. '4 an enlarged detail view of the special key and connection with the usual total"key of the machine; and Fig. 5 a detail 7 I have provided Ito prevent -'the operation of certain of the type ievers.

Inasmuch as, in the present instance, my invention comprises an attachment to the well :known Burroughs adding machine substantially as disclosed in said prior Burrough's patents, the old parts wiil be designated as in such patents and only those old parts will be considered which are concemed directly with my invention. r

The machin has a keyboard provided with a plurality of rows of keys 221,;e'x-

tending from front to rear of the machine,

view at the sliding plate which enable a total to be taken whenever desired by the operator. The levers B, which correspend in number with the rows of keys, are hung upon the main rcc'k shaft 600, Fig. '2, rearwardly extending sector-shaped arms 61-1 carrying the usual type-plates 618 and provided with forwardly and downwardly'exte'nding arm's 611 operatively connected with a geartocthed rack '610. The movements of this rack are controlled and determined by the rods 270 operated and set by the keys 22 in the well known way. The series of racks 610 cooperate with a corresponding series of adding wheel pinions '916 which are swung out of mesh with the racks upon the forward movement of the 'o eratin-g handle 367, and downward movementof the racks, but swing into mesh therewith upon the rearward movement of the operating handle and upward movement of those racks which had been released,with the result that the pinions, corresponding to the particular racks released, are turned by such racks distances corresponding to the previous down- 45 thetotal key 265 is held depressedonly durward movement thereof. To this end, the

inicns 916 are mounted in a swinging frame consisting of two arms C located at opposite sides of the machine andsecured to a rock shaft 900 journaled in the frame thereof. This frame is limited in its back-- ward and forward movements by the engagement between the bifurcated end of the a v the result that ciphers will be printed by 18 adapted to be swung,

arms C and a stop 205.

The pinion frame by the movements of the main operating lever 367, by means of the arm 911 and the three-armed lever 913 to which theformer is pivoted at its rearward end. This arm 911 is supported near its forward end by the long substantially vertical link 911 operatively connected at its upper end with the bell crank 227 of the total key 265. The front end of the arm 914 has two diverging arms or branches 914* and 914: adapted to cotiperate with and engage the swinging pinion frame, with the result that the pinions are removed from engagement with their racks and reengaged therewith at the proper times in orderthat upon the upward movement of the released or operated racks I the pinions will be turned distances orresponding to the previous downward movements of the respective racks.

As is well known, the depression of the total "key 265 during both forward and rearward movements of the operating handle 367, enables a total to be printed and the machine to be sequent swinging of the arm 911 by the link 911 permits the inions to remainv in mesh with their racks during their downward movement, with-the result that such racks are permitted to descend distances corresponding to the values of the'adding wheels associated with such pinions and the levers B and their-type upward corresponding distances, whereby the total will be printed. In printing a subtotal and therefore not clearing the machine,

ingthe forward movement and is released prior to the backward movement thereof, with the result that the pinions will remain in mesh with their 'racksin both movements of the operating handle, such pinions, after the printing of the sub-total, being restored to the positions which they occupied rior to the downward movement of the rac 's.

The printingmechanism of machine-1s so well known as not orequire any detailed description, andit will therefore suffice to-Say that the movable type plates 618 upon-the respective levers are forced rearwardly against the platen 619 by means of the hammers or strikers which are actuated by latches in the manner fully ex plained in said Burroughs patents. In this connection it may be stated that upon the first forward movement 9f e operating cleared, inasmuch as the con-- plates to be raised or swung Burroughs V handle the rearward ends of all$he levers carrying the type-plates are swung upward-thosewhicli have been set. or operated by the keys being swung a distance corresponding with the value of such keys and I those' which have not been set being swung slightly so as to bring the cipher of their upper type plate in printing position, with the levers which have not been operated or set by the keys, owing to the tripping of their latches by left. Of course, this tripping takes place with relation to the latches on the right so that ciphers will never be printed to the left of any figure.

chine, so far described, is that of the well known Burroughs adding machine, sufiicient of which construction having been explained to afford a clear comprehension of my invention, now to bedescribed.

the adjacent latch on the The construction and operation of the ma- Before proceeding to a detailed explana- I 'ti'onof'my invention, it will be observed that-the ob]ect thereof is, ,in general terms,

.to render the adding mechanism of the machine inoperative at the will of the'operator whlle permitting the printing mechanism to perform the'usual functions, excepting'that, in the construction herein shown, a certain predetermined number of the levers and rows of keys on the right hand side are rendered inoperative when the printing (without addition) is being done, for whichpurpose the remaining levers and. rows of keys on the left are employed. For the purpose of more clearly indicatmg and. distinguishing between the old and new parts, I have, in the drawings, shaded the new parts andhave left the old parts in outline.

A supporting plate 1 is arranged at the left hand side of the machine and provided with a pin or stud 2 constituting a fulcrum for a substantially horizontal lever 3 extendmg forwardly adjacent the total key connections, and rearwardly adjacent the pIll'lh-I 1ng mechanism. As shown in Figs. 2 and 4, the forward end of the lever?) is connected to the lower end of the stem4 of a special key 5. This key stem has an offset or shoulder 6 adapted, when depressed to'bear upon the upper edge of, the bell crank 227 and rock the latter in the same manner as when ammo ward-1y to inoperative position as usual, and such pinionsremain in such position so long as the special. key is depressed, with the result that the adding feature of the ma chine iseliminated as to operation and the printing feature alone utilized, at the will of the operator.. 2

7 position. The chine are thus Referring to the herein illustrated embodiment of myinvention, when the special key 5 is depressed the total key and is connec-' tions are moved to a slight extent but sufficient to prevent the arm or lever 914 (on its rearward stroke) from returning the adding wheel pinions to mesh with their racks without affecting its preliminary function (on its forward stroke) of throwing such pin ions out of mesh. Referring particularly to Figs. 2 and 2 the adding wheels,- normally, are in engagement or mesh with the make, but when an item or amount is set up on the keyboard, and the-special key 5 is depressed and the arm or lever 914i pressed or swung down to a position intermediate its two regular positions, and when the machine is operated, such lever 914 moves forwardly, as usual, on the first or forward strokeof the operating handle, its

upper and rearward finger or prong 914 contacting the pin 958 thereby throwing out tis adding wheels. During the return movement of the operating handle, the lever 914 is moved rearwardly, as usual, but, owing to the depressed position, to which it is held,- its other finger or prong fails to strike pin 958 onframe C as heretofore, in order to return the addingwheels to coeperative relationship with their racks, and conse quently the adding wheels remain in mop-- erativ'e position. Nor does the lower hook 914 accomplish the result of returning the adding Wheels, for it is not in a low enough adding wheels of the mathrown out, as usual, at the beginning of the movement of the operating andle or lever, but owing .to the movement of the lever 914 to its said intermediate position, such wheels are held out" until such 'cient to accomplish the handle returns to normal position: Mean while,

the amount or item set up on the keyboard has been printed by the machine, but" not accumulated. a In the regular operation'o'f the total key or button,

the act of depressing the same causes a releasing and restoration of any value keys which may have been operated but, as hereinshown, the arrangement is such that the act of depressing the special key and the consequent slight depression of the total key and connections, While suii'iitemporary elimina tion of the adding function of the machine,

of releasing and restoring the operated key or keys, but per inits such keys to remain set and the amount represented thereby to be printed without is thereby de= a (Fig. 3),

ranged to slide freely upon,

the cross rod 202 which is movable in the" longitudinal slots 229 of the arms 229 in advance of the usual sliding bars 214. When any value key is depressed, its bar 214 is slid a short distance to the rear, and, in order to restore such bar, the total key 265 maybe depressed with the result that the cross rod 202 is swung forwardly against the operated bar which is thereby forced hack to normal position, However, the rod 202" moves a short distance forwardly bei ore contacting with the rearward end of the operated bar 214 and it is this idle movement only that the operating of the special key 5 can accomplish so that while the act of depressing the special key does indeed cause the rod 202 to be moved in the direction of the ends of the bars 214, such movement is not sufficient to force them to normal and thereby cause a restoration of the operated keys on the keyboard.- The action of the special key thus has no material effect upon the key restoring mechanism, but through the medium of the totalizing mechanism positively eifects the adding or aocumulating function of the machine, besides which, according to the present construction now being described, the same act of'eliminating the adding function of the machine results in rendering inoperative the print ing mechanism corresponding to a predetermined number of the denominations represented on the keyboard, as now to be eX- plained.

The rearward end of the lever 3 is bent inwardly toward the printing mechanism and is operatively connected to the lower arm 7 of a bell crank which is pivoted at 7 to a fixed point on the machine frame The upper arm 8 of this bell crank is slotted to receive the bent end of a horizontally movable rod 9 passed through the end plates 510 of the ribbon frame or guide and supported and guided thereby.

The right hand end of the rod 9, which is movable longitudinally, is adjustably secured to a sleeve 10 encompassing, and arthe usual stay rod 503 which supports the plates 510 of the ribbon frame or guide. .Depending from this sleeve is a curved Wing or blade 11 movable with thesleeve 10 and in a vertical plane. The lower end of this blade is in substantially the same horizontal plane as the top edges of the series of levers B when in normal condition, and the width and the degree of movement of the blade to the left is such as to interfere with the movement of a predetermined number of the levers B beginning on the right hand side. In the present instance, the blade isarranged to interfere with and prevent the operation of the levers corresponding with the five rows of keys of the lower denominations, leaving the remaining four rows to, serve for printing purposes when the special key referred to is-operated. In orden to be guided, the lower end of the blade travels ina cross slot 7 23 in the upper edge of the usual link or bar 723 which supports the lower end of the ribbon guide frame at one side. The adjustment between the rod 9 and its sleeve 10 may be obtained in any,

suitable manner, and in the present 111- stance the right hand end of the rod 9 passes through a lug" 12 and is screwthreaded to receive an adjusting nut 13 arranged to bear against one end' of the lug 12. A spring 14: fastened at one end to the blade 11 serveslto hold the latter hand position.

Normally the blade 11 is positioned at one side of the levers B as indicated by full lines in Fig. 3, but upon the depression of the special key 5, the rearward end-of the lever 3ais rocked upward and the lower arm 7 of the bell crank is likewise rocked in the same direction, the rod 9 is moved or shifted longitudinally toward the'left hand side'of the machine (Fig. 1), or toward. the right when v ment' otthe rod 9 the viewing the machine from the rear as' in Fig. 3, where the dotted lines indicate the shittedposition of the parts. By this moveshifted laterally ina position immediately above five of the levers 'ncmination. These five levers are thus rendered inoperative, and, moreover, their ham- ,mers are also rendered inoperative 1nas-' much as the blade is interposed in their path, thereby preventing them from strik-" ing the type plates oft-hese particular levers. The object of thus rendering these five levers inoperative is to eliminate that portion of the machine associated therewith and leave the remaining mechanism absolutely free and uninterfered the purpose of printing numbers, with the result that any accidental setting of the keys in any of the-five rows corresponding with these five inoperative levers will not interfere but will be negatived Moreover, the positioning of the blade immediately above the levers and interposing the same in the path of the vfive hammers on the right, prevents the levers from rising and the hammers from striking, with theresnlt that no ciphers or other characters are or can be printed at the right of the figures or numbers printed by the left hand side of the machine during the same operation or movement of the operating handle.

It will be understood by reference to the ahovementioned Patent 595,9?8 that the hammers are reieased by the action of pawis to its right with the result that particular blade orwing 11 is B of the lower dewith for in withdrawing detaining latches from engagement with hammer-driving levers and further that these pawls are disabled by the contact of their tails with inclined shoulders on the type-carrying levers when such levers are not moved in obedience to depression of amount keys. Hence of course the holding down of type-carrying levers in the manner described will cause the pawls associated with such levers to i be disabled. However, as hammers may be released notwithstanding pawls, in order to provide for a filling in of ciphers as explained in said Patent 505,078, the blade is arranged to intercept such hammers as already explained. While the aforesaid plate will thus intercept five hammers when thekey 5 is fully depressed, a less number of hammers and a correspondingly less number of levers may be intercepted by partial depression of said key. In tact,

disablement of associated the number can be varied from one to five by regulating the degree of depression of the key 5. t

In. practice, transactions, the operator utilizes the four rows of keys on the left and sets the keys according to the identifying number of the cotton balef Ordinarily z-if the machine should now be operated, a row of ciphers would be automatically printed to the right of the figure ornumber printed according to the keys set, but to prevent this and also to throw out the adding mechanism orfeature ofthe machine at this moment in the operation of the machine, the parts-eonstitutmg myinvention are brought into action by the operator by depressing. the special key 5, with the result that the blade 11 is moved laterally to interfere with the movements of the five levers B on the right and the arm or lever 91% is depressed 'or shifted sothat the adding pinions will be thrown out of mesh with their racks when the operating handle is manipulated. The result 1s that the number of the bale of cotton will be printed, for the machine, under the conditions named, now acts simply as a printing machine. The special key is now released, andthe operator then sets the keys of the right hand' rows (which had previously been rendered inoperative) according to the price of the bale of cotton, and upon operating the machine the price is printed and referring to cotton bale and registered on the adding wheels. .This I latter operation is usual operation of chine. f N

The operations just described are repeated for each transaction, with the result that the numbers of the bales will be printed (without addition of course}, and the prices thereof will he likewise printed but will in addition he totalized, so that a trital can be precisely the same as the a Burroughs adding metaken at any time, in the manner well known to users of Burroughs machines. #The 1 machine isthus normally capable of both pfiinting'and addin ment's, the machine is capable of eing, in elfectfdividedinto two'parts, *one capable of'printing without adding and the other atthat time incapable of either'printing or adding; In other words, one-part of the machine is rendered entirely inoperative :printing and when the other part of the machine is'used for printing only. In this manner, a num- 1 her. which is notrequired to'be added may be printed by the machine at the left side of= w a sheet of paper, and-a number to be addedmay be printed at the right side thereof,

both said respective numbers being listed but only one set ofnumbers being totaliz'ed.

My improved machine may be used for a ing of numbers requiring to'betotalized and the simple printing of'other numbers-not requiring to be totalized. "My machine-is therefore not limited in its usefulness to -merely accounting cotton sales, which is taken as a convenient and slmple illustration or example of the character of the work of which the improved machine is capable. It is evident that the keyboard and -ma chine generally may have any desired =capacity, but the machine shown, with its nine rows of keys of different denominations, will be found sufiicient for man ordinary transactions, such as the'accounting of cottonbale sales, for in the present -machine herein illustrated the four rows of keys on the left of the key board are sufficient tti the five remaining rows are sufiicient to take ""care' of theprices to be listed and totalized- 'two functions or Moreover, 1t is evident that the-blade may be adapted to cover'or interfere with more or less of the levers, and thereby lessen or decrease the range, of the machine for-the purposes stated.
